Over the next years the system is going to be refined.
There is -as always- scope for improvement. There are on the one hand obvious candidates such as cost reduction while maintaining quality and design. There are, however, essential technical improvements that can be made without compromising the simplicity in design, e.g. making the connection between player and amplifier purely digital, even galvanically separated such that the amplifier only receives data and carries out the conversion and amplification.
Another source for improvement is the much valued customer. Any suggestions that are in line with the design philosophy of the product are very likely to be incorporated.
